To all whom it may concern: v Be it known that I, LAURENT .RONDOLIN.

a subject of the King of Great Britain and Ireland,- residing at 'Bermondsey, in the county of London, England, have invented Improvements Relating to the Manufacture of Biscuits and like ltdible Articles and -Means Therefor, of which the following is a; specification.

This invention relates to the manufacture of biscuits and like'edible articles according to which a plastic mass in sheet form is both impressed and cut and more particularly to the manufacture of biscuits or their equivalent by means of shell cutterswithin which work impression blocks or dies.

According to the present inventionthe inanu-facture as aforesaid is improved .by

arranging that the sheet mass shall be first acted upon by the cutter to a limited extent and thereafter by the impression block or die. In this way the shell "cutter acts to confine the mass sufficiently to prevent undue spread and consequently ensure enhanced formation by the impression blocker die.

A further feature of the improved method consists in causing the limited or partial cutting operation to be resumed only after the impression block or diehas come to rest by which time all excess material will have been displaced beyondthe knife edge Yet another feature of the improved method consists in causing the biscuit blanks tobe released from the action of the impressionfblocks or dies before the cutters are withdrawn from the sheet material. 7

The means forcarrying out the invention mavhomprise any convenient arrangement otblo'cl": and cutter heads and mechanism for securing the'operations respectively re ferred to, but itis considered advantageous to impart motion to the cutter head through the companion head of the impression blocks, the two being resiliently connected together and movement 'controllingmeans being associated with the cutter head as hereinafter set forth.

But in order that the invention may be more readily understood it will now be further described with reference to the accompan ing drawings whereof Fig. 1 is a part sectional elevation of so much of one eon- V struct-ional form of machine as 1S necessary to elucidate the action. Figs. 2 and 3 are springs j.

are of well known type so that they at no 1' time project therebeyond, the position at the commencement of a cycle of operations, as at A Fig. 4;,"being such-that the blocks a are at'a maximum distance from the edges ofthe cutters '0 andnncover vent holes V in the walls or shells of the cutters; The

blocks proper a,-,ignoring the impression faces, may be of uniform cross section and. pass through holes in a cutter head 7 which cutters c and be connected to a head 9 which either may be auxiliary to a beam h or, itself constitute the beam, adapted to be positively operated or actuated, 2' representing the arms such as are customarily employed for the purpose. r I

The head f. for the cutters may be sepa correspond in shape to the shape of the i rated from the head 9 or beamfh forjthe impression blocks a by stiff springs suchas shownat Fig. 1, so that they move in unison except at timeswhen means are brought into use to arrest or modify the movement. Asexemplified, the cutter head f is connected by'pillars 70 to plate in having tails a, which work in guides 0 in the beam 7L, and'are attached to'screw threaded rods 1) passing throughthe-latter andthe The upper ends ofthe rods p are secured to a beam 9" provided witha 1 pair of wearing plates 8 cooperating withia pair-of edge'check cams t driven in any suitable way as by bevel gearing it. Means such as bevel gearing 1) upon the beam 1" enables the position of the beam 1" to be adjusted by hand in relation to the mem bers f, g, h w being correspondingly a'd-- justa-ble stop nuts for determining the position of the head f in relation tothe head g. The whole arrangement is such that'c'o'rn mencing with the initial position of the parts referreclto, eorrespondin to A El 4c, the cutters c and impression leeks an I Vance collectivcly toward the sheet a? of dough, there heingno nioveinent between the cutters and blocks until the cutters have ent red the dough to the desired degree as at Fig. '4, when they arearrested bythe cams If, the blocks a continuing to advance and any air..which niight.tend. to become imprisoned being released the vent holes (Z.
